Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619888, here are decompositions:

  • 5 + 8619883 = 8619888
  • 19 + 8619869 = 8619888
  • 29 + 8619859 = 8619888
  • 31 + 8619857 = 8619888
  • 71 + 8619817 = 8619888
  • 97 + 8619791 = 8619888
  • 227 + 8619661 = 8619888
  • 239 + 8619649 = 8619888

Showing the first eight; more decompositions exist.
